    Abstract: Connection systems for use in fiber optic communication networks and systems are disclosed. Embodiments of backplane connection systems are disclosed that include a daughterboard connector that can make with a backplane connector. One of the connectors can include a movable latch element that can bend a bendable arm on the other connector to latch and unlatch the connectors. A connector can include a movable blocking element that prevents a latch control element from moving its full range when the connectors are disconnected. A latch control element can have a range of motion along which it maintains the connection system in a latched configuration. A mounting system is also disclosed that permits a connector to flow or move along the board in a limited range of motion with respect to three axes.
